Application filed November 18, 1918. Serial No. 263914.

To all whom it may concem:

Be it known that I, J OHN'HEMFLING, Sr., a citizen of the United States, residing at New Germany, in the County of Carver and State of Minnesota, have invented certain 'new and useful Improvements in Wreckingremoved, the tool being constructed to pre-` vent mutilation of the boards as much as possible.

More specifically, the .invention comprehends the provision of a Wrecking tool, the handle of which has one end flattened to serve as a pinch bar, while the other end of the handle curves downwardly, oppositely to the curvature of the'beveled end of the handle and has a head carried thereby comprising a pair of tangs which are spaced equidistant upon each side of the handle and have their upper surfaces concavely curved, the under sul-faces of said tangs being curved upon a smaller radius than the upper surfaces, resulting in the beveling or sharpening of the outer ends of the tangs to facilitate their insertion beneath the various boards to be removed; 'and also to provide a cam surface upon the under side of the head of the tool, the end portions of which cam surface are rounded and intermdiate portion of which is flattened and roughened toserve as a hammer head and also prevent slipping movement of the tool during use. The said cam face or elargement projects outwardly from the outer face of the head, being connected to the shank by a concavo-convex shoulder which serves' as a fulcrum during the initial pivotal movement of the tool to pry a board loose from its fastening, and which also serves as a fulcrum when the tool is used for Stretching barbed wire or analogous material, the said operation being performed through the medium of the claw portion which extends rearwardly from the downturned portion of p the handle and the cam surface.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanyng drawng, forming a' part of this specification and n which drawing:

Fgure 1 is a side elevation of the improved wrecking tool showing the same in use for removing flooring boards.

F lg. 2 is a plan of the tool showing the same as used fo removing lath or analogous boards.

3 is a side elevation of the tool showmg ts application for stretching wire.

ig. 4 is a fragmentary perspective of the tool, and

Fig. 5 is a f'agmentary bottom elevation of the tool. p Referring more particularly to the drawng, 1 indicates the handle of the tool which is preferably polygonal in shape, so as to pel-mit the more firm grip thereon. The outer end 2 of the handle is beveled and curved slightly from the longitudinal line of the handle, forming a wedge or pinch bar end, upon the handle 1 the use of which may be necessary during the wrecking of a building.

The end of the handle opposite to the beveled end 2 is curved, as shown at 3, in the direction opposite to the curvature of the beveled wedge end 2 and it has a head 4 fol-med upon the lower terminal of they curved portion 3.

The head 4 comprises the laterally extending portions 5 and 6 which extend-laterally from the sides of the handle an'd have the spaced tangs 7 and 8 formed thereon at its outer end. The said tangs 7` and 8 are spaced a suflicient distance to permit them to engage boards one upon each side of the joist or stud to which they are attached, as clearly shown in Fig. 2 of the drawing. The upper surfaces of the tangs 7 and 8 are concavely curved while the under surfaces are curved on an arc of less radius than the arc of the upper surfaces of the tangs resulting in the consequent beveling of the outer free ends of the tangs as shown in the drawings, to facilitate the insertion of the tangs -beneath boards in such manner as to permt the removal of the boards without marring them to any material extent. The

.under or outer surface of the transverse or lateral portions 5 and 6 extends outwardly from' the under surfaces of the tangs 7 and 8 and is rounded, as is also the rear surfaces of the said lateral portions to form a cam face which acts as a fulcrum for the pivotal movement of the tool in prying boards free and to form a rounded shoulder on the from the studs or joists to which they havebeen attached. The forward lower edge of the cam or fulcrum member of the tool 'is rounded and merges into the under arcuate surface of the'tangs 7 and`8 bythe concavo convex shoulders indicated at 9 which, when the tool is used for stretching wire as shown in Fig. 3, .engages upon the fence post A,

while the wire indicated at B is engaged in" e I 4 are flat forming a flat stop for engagement with 'the joist or stud to arrest the pivotal movements of the too-1 during, the removing; of boards( A portion' of this flat surface, namely the portion which is directly beneath the terminal of the lower-curved portion 3 of the handle 1 is roughened as' shown at 12 to prevent accidental slipping of the tool duringuse and also to serve as a hammer head when necessary. r

From the drawing, it will be noted that the tangs 7 and 8 commence at'the .outer most portion'of the conveX sideof the curved portion 3 ofthehandle, and while certain uses of the tool have been illustrated in the drawings and described in the foregoing description, it is understood that the tool may be utilized for any similar or analogous purpose which may arise.

Changes in details may be made without 1cleparting from the spirit of the invention,

I-claim: 1. A wrecking tool comprising a straight bar forming a handle having one end curved, a head formed upon the, terminal of the curved end and com'prising lateral extensions on the handle, and a pair of spaced tangs extending from said lateral extensions parallel to. each other and to the handle, said tangs having concaved upper surfaces and convexed lower surfaces, the under surfaces of said lateral extension `projecting below the under surf-ace of the tangs and rounded to form a cam surface acting as a fulcrum for pivotal movement of the tool under surface of said head.

2. A wrecking tool comprising a straight bar formng a' handle having one end curved,

a head formed upon the terminal of the curved end and comprsing lateral extensions on the handle, and a pair of spaced tangs extending from said lateral extensions parallel to each other and to the` handle,

said tangs having con-caved upper surfaces and convexed lower surfaces, the under surfaces of said lateral extension projecting below the under surface of the tangs and rounded to form a cam surface acting as a ful-crum for pivotal movement of the tool and to form a rounded shoulder on the under surface of said head, a claw formed upon said head .and extending rearwardly from .the head, said claw having its under surface flat and flush with the under surfaceof the extension to forma stop for limiting pivotal movement of the tool upon the cam surface as a fulcrum.

3. A wre'cking tool comprising a straight bar forming a handle having one end curved, a head formed upon the terminal of the curved end. and comprising lateral eXten-' the under surface of the tangs and rounded' to form a cam surface acting as a fulcrum for pivotal movement ,of the tool and to form a rounded shoulder on the under surface of said head, a claw formed upon said head and extending rearwardly from the head, said claw having -its under surface flat and flush 'with the under surface of the eX- tension to form a stop for limiting pivotal movement of the 'tool upon the cam surface as a fulcrum, a portion of the under surface of said claw being roughened. g

4. A wrecking too-l comprising a straight bar forming a handleand having one end curved, a head formed upon' the terminal of the curved portion and comprising lateral extensionsof the handle, a pair of spaced tangs extending from-said lateral extensions parallel to eachother and to the handle the under surface of said lateral extensionsprojeoting below the under surfaces of 'the tangs and being rounded to form a cam surface acting as' a ful-crum for pivotal movement of the tool, and a rounded shoulder on i the' under surface of said head, the upper rear edge of said extensions being rounded JOHN HEMFLING, sn.
